In decision making we have to get the experts decision choice about criteria and alternatives. So, my question is there any methodology besides DELPHI to get that .
Another stream that provides insights in decision making is the data-intensive decision making. It uses techniques like simulation (so, you have to built your model, find the appropriate data, calibrate it and run it), recommender systems and data mining. First of all you have to define your decision making process (in business or in public sector). You probably have to decide on what the decision making life cycle is and model it (e.g. policy modeling).

What about the AHP: https://en.wikipedia.org/wiki/Analytic_hierarchy_process
1. Brainstorming:It is a combination of group problem-solving and discussions. It works on the belief that the more the number of ideas, greater the possibility of arriving at a solution to the problem that is acceptable to all. It starts with the group generating ideas which are then analyzed, with action points based on the discussions.
For instance, if you have received a new e-learning project and are thinking of a strategy to implement in the course, you can follow this technique. Gather a group of instructional designers in a conference and let them first analyze the inputs. After that, you can collect ideas from each of them and take the final decision.
2. Nominal group technique:In a nominal group technique, the team divides itself into smaller groups and generates ideas. Possible options are noted down in writing and the team members further discuss these to narrow down the possible choices they would like to accept. Team members then discuss and vote on the best possible choice. The choice that receives the maximum votes is accepted as the group decision.
Continuing the above example, this group of instructional designers can be further divided into smaller teams. Every member of the team gives their idea and at the end, each member votes for the best one. At the end, the idea that gains the highest votes would be finalized.
3. Multi-voting:It starts with a round of voting where an individual casts his vote for the shortlisted options. Each individual can cast one vote at a time. The options with the maximum number of votes are carried to the next round. This process is repeated until a clear winning option is obtained.
For instance, from the above discussed example, each team would propose their strategy in front of the other teams. And the other teams would vote for the one they prefer best. The strategy that receives the maximum number of votes is considered final.
4. Electronic meeting:Here, the decision-making process takes place virtually with the help of technology. For instance, we can have a Skype call with the client. Create two or three strategies and discuss them with the client clearly in the Skype call; let the client choose the strategy close to his expectations.
Team decision-making is a time-consuming process and before the team leader ensures the participation of the full team, he/she must make sure he has enough time and resources for the decision-making process and choose a technique that is most appropriate in a given situation, keeping the profile of team members in mind.
As suggested by Susanne Strahringer, you can use AHP. Analytical Hierarchy Process (AHP) is a simple multi criteria decision making method developed by Thomas L Saaty. you can can read about AHP here :

If you are new to AHP, there is a two part video in youtube which is really helpful. Following are the links for the video:

Another of the methods for making decisions is the method of the experts that employs the coefficient of Kendall. The only detail is to validate the experts. For this, the methodology of Oñate Ramos (1998) can be used to determine the coefficient of agreement of the experts. Dianelys Nogueira and Alberto Medina have some work related to the subject.
Hello,
You can use Kendall Coefficient of Concordance. Check the work below for more details:
